head members by tie rods which willetake i the tensile stresses which have to be borne by the frame of the type of presses in question and neutralize, or obviate the shearing stresses that tend to cause the frame parts sliding on one lanother.

In the accompanyin drawings,

Figure 1 is a side e evation of a cutting press frame embodying my invention;

Fig. 2 is a front elevation thereof;

Fig. 3 is a detail view, in side elevation of a built-up form of tie rod; and

Fig. 4 is a side elevation of a press having a one-piece frame, embodying my invention.

Referrin to the cutting press frame shown in igs. 1 'and 2, it will be seen that it is composed of a base member 10 having a plane, or flat top, a head member which is composed of two similar elements 11, which have half boxes 12 to furnish 'bearings for the shaft which extends from side to side of the press, and a body member 13, which, at its lower end rests upon the base at the rear thereof, the two being secured together, and at its upper end at each side has secured to it the two elements forming the head member 11, the abutting faces of the various members bein plane, or flat. The body member 13 inchnes upward and forward so that as will be seen from Fig. l of the drawings the ram reciprocating shaft overhangs the work on the bed 0f the Press upward `through o peningS,-'1I.. the? body-13 andthehea-d .elements 1liend emerging 012#` the -toplofathelattei satie. rodfstuated that itis .intermediate the illcrurn, `or ,baarn4 ing Aspoi'ntslepen., which .the-.body member; 11h41@ leads.- ftendsf .to roth... uponrthefbase; flu and the line of thrust betweenfthe shaft sans ported by the head elements llgandthebase, sothatxhatiereds are-gpraetieell in .the line 0i seete t-tensilefstrains and@ @metete the tensile .Stress thigh the frame-hust been In. its.- loven Qrtlen.; and for substantiels halfg .is le# Vitiai Stioil pro-71 blinding end .has .e irait 1'? :that bears. against theres eredeef't @base-.10, @edits inertie. isfbraeehe @Een @lds0- ldetienearf1f11fel?. meterle ses j.. ,toward est the .ethelf @H1149 .-llleneeflipwetd .and meer@ ward, and both arms pass thrdghlthehead releerlas -lzl Qaedafabnveetheelatteneaed .beth barriga-,thus oblique to the plane of the 'oint between the head element 11 and the body has a nut 20. that bears against the upper side of the head element.' Since the lower vertical portion 16 of the tie rod reaches through the base 10 and the body member 13 and extends at right angles to the plane of the joint between them, said portion 16 is under tensile stresses that are normal to said plane, and hence, no shearin l stresses parallel to such plane are set up an accordingly,- no tendency is caused for the sliding of the base and body members relative to each other. The forward inclination of the fork arm 18, by carrying it closer to the point of upward thrust exerted on the head element 11, enables it the better to resist such thrust by taking tensile stresses, but as it tends to straighten up, or shift backward under the pull upon it, it sets up a tendency of the head element 11 to slide rearward over its bearing upon the top of the body member, but as the other fork arm 19 inclines in theopposite direction, and hence, under pull upon it, tends to move forward, it neutralizes the corresponding, but oppo' site action of the other fork arm 18, and, hence, horizontal shear, or tendency of head element to slide on the top of the body member is prevented.

The tie rods may have the integral, or one piece form shown in Fig. 1; or the built up member 13. Each the tie .sed has Streghe a:
